In a series of coordinated raids, the FBI and London’s Metropolitan Police raided the homes of several suspected Anonymous and LulzSec members, nabbing what authorities in the UK think is one of the core members of LulzSec in the process.

In New York yesterday, FBI agents spent over an hour executing search warrants at three different homes in the New York area, removing laptops and other computer equipment from suspects’ homes before taking them into custody. In similarly timed raids, FBI and local authorities detained at least 14 other suspected Anonymous members and executed over 35 search warrants from New York City to Florida to New Mexico.

At the same time, in the UK the Metropolitan Police arrested a 16-year-old in South London who goes by the handle “T-Flow,” and charged him with violating the Computer Misuse Act. T-Flow, authorities suspect, is one of the central members of LulzSec, and had a hand in coordinating a number of its most high-profile activities, including LulzSec’s latest hack: redirecting the front page of The Sun newspaper to a false story reporting Rupert Murdoch‘s death.

Shortly after those raids, Dutch police arrested another four individuals in the same investigation. Authorities are hoping they’ve put a significant dent in LulzSec and Anonymous’ operations with the new arrests. However, even though the police have made their arrests, it’s unclear whether all of the users will be charged, or if authorities will find enough evidence to prosecute any of the people they’ve detained.
